  • Product-oriented thinking: You care about delivering meaningful features that create value for users and improve the overall mobile experience.
  • Collaborative communication style: Strong communication skills and enjoyment in working within cross-functional teams, contributing positively to engineering culture.
  • Security and compliance awareness: Understanding of mobile security best practices and data protection requirements.
  • Nice to have: Advanced experience with native Android development, native module integration, performance optimization, or offline-first architectures.
  • Language skills: Fluent in written and spoken English.
What we offer:
  • Flexibility for Your Lifestyle: Enjoy family-friendly working hours and a generous home office policy, allowing you to stay agile and flexible in any situation.
  • Ergonomic Work Environment: For your office days, we provide ergonomic workstations that offer you a comfortable and healthy workspace.
